Hello,
I don't manage to run more than one FTDI Usb Serial Adapter on a
Beagle Bone Black. Since there is only one Usb Host port on the BBB, I
tried with several hub (powered or not) or cape.
Each time that more than one adapter is plugged, these errors appear
(kernel 4.4 or kernel 4.9):

Add some simple script which creates a USB gadget using ConfigFS
and then exports it using vUDC.
This may be useful for people who just started playing with
USB/IP and vUDC as it shows exact steps how to setup all stuff.

Now races can happen between interrupt handler execution and PM runtime in
error handling code path in probe and in dwc3_omap_remove() which will lead
to system crash:

Hi!
While running the syzkaller fuzzer I've got the following error report.

smbencrypt() points a scatterlist to the stack, which is breaks if
CONFIG_VMAP_STACK=y.
Fix it by switching to crypto_cipher_encrypt_one(). The new code
should be considerably faster as an added benefit.
This code is nearly identical to some code that Eric Biggers
suggested.
Cc: sta...@vger.ker
Eric Biggers found several crypto drivers that point scatterlists at
the stack. These drivers should never load on x86, but, for future
safety, make them depend on !VMAP_STACK.
No -stable backport should be needed as no released kernel
configuration should be affected.
Reported-by: Eric Biggers
Eric Biggers pointed out that the orinoco driver pointed scatterlists
at the stack.
Fix it by switching from ahash to shash. The result should be
simpler, faster, and more correct.

The Hi6220's usb controller is limited in that it does not
support "Split Transactions", so it does not support communicating
with low-speed and full-speed devices behind a high-speed hub.
Thus it requires a quirk so that we can manually drop the usb
speed when low/full-speed are a
From: Chen Yu
We've seen failures when switching between host and gadget mode,
which was diagnosed as being caused due to the bus being
auto-suspended when we switched.
So this patch forces a port resume when switching to device
mode if the bus is suspended.

When removing a USB-A to USB-otg adapter cable, we get a change
status irq, and then in dwc2_conn_id_status_change, we
erroniously see the GOTGCTL_CONID_B flag set. This causes us to
get stuck in the "while (!dwc2_is_device_mode(hsotg))" loop,
spitting out "Waiting for Peripheral Mode, Mode=Host"
I've found when booting HiKey with the usb gadget cable attached
if I then try to connect via adb, I get an infinite spew of:

I just wanted to send out my current queue of patches for dwc2
controller on the HiKey board.
This does exclude my patchset[1] to add extcon support to dwc2,
which John Youn suspects a pending rework of the dwc2 fifo init
logic might make unnecssary.
So in the meantime, I wanted to send out the o

For some mobile devices with strict power management, we also want to suspend
the host when the slave is detached for power saving. Thus we add the host
suspend/resume functions to support this requirement.

Changes since v4:
- Remove Kconfig and just enable host su
Enable the xhci plat runtime PM for parent device to suspend/resume xhci.
Also call pm_runtime_get_noresume() in probe() function in case the parent
device doesn't call suspend/resume callback by runtime PM now.
